It seemed to me that something different was being proposed. During
the execution of the block, the object associated with 'self' is
augmented with additional methods.  When the block finishes the
additional methods are withdrawn.  It isn't the message dispatch
mechanism that is changing but instead the included module list of
the object's singleton class is being temporarily modified.

So in your example, 'm' and '@v' are still evaluated relative to
the same 'self'.
